How to display the travel card of the mobile secondary card

There are many methods, listed as follows:

Make the mobile phone automatically connected to the network, and make short message inquiry: send a short message CXMYD to its affiliated operator (telecom 1000 1/ mobile 10086/ China Unicom 100 10) for inquiry;

Unicom users can send CXMYD. The last four digits of this mobile phone number correspond to the ID number to 100 10, and you can query the roaming information of 14 days.

If your travel code can't be displayed, it may be because the network signal is not good, or the mobile phone is out of order, which leads to the failure of the travel card system. You can refresh the network or restart the phone.

I hope my answer can help you!
